50,8mm extension tube 45mm

Quick Overview

The 50.8mm extension tube 45mm fits into any 50.8 mm diameter focuser and extend by 45mm the same connection. It's therefore very useful when the focus point of the telescope is too much outside, as often happens when you want to connect a camera to refractor telescopes.

Equipped with a high mechanical quality and excellent finish, this extension has an inner brass ring to avoid damaging the accessory inserted which is locked with the large knurled screw. At the bottom, the extension tube has a M48 thread to allow you to connect the filters (such as those against light pollution).
